DISCHARGING MECHANISM FOR PAPER-FOLDING MACHINES.

A plication filed May, 4,

This invention relates to paper folding machines andmore particularly to a dise.

' gagement one with another and will prevent tilting, falling or rumpling of the folded papers. 1 Anotherobject of the invention is to pro.- vide a discharging mechanism which comprises means fon'preventing the last folded paper discharged frominterfering with the discharge of the succeeding foldedpapers.

. Another object of this invention is to .provide a counting mechanism for automatically counting a predetermined number of the folded papers and moving the last paper of each predetermined number into staggered relation relative to the remaining foldedpapers, tofacilitate the binding of the folded papers in packages containing a predeter: mined number of the folded papers.

Another object OftlllSlIlVGIltlOIlllS to provide a discharging andcounting mechanism which is applicablefor use upon the napkin folding machines as disclosed in the ,applications on napkin machines, filed April 4, .1922, Serial No. 5 19,5341 and September 22, 1922, SerialNo.589,834.. 7 I

Other objects of the invention will appear in the following detailed description taken in connection with-the accompanying drawings wherein:- w Fig. 1 is a view in side elevation showing parts insection, of the discharging mechanism. I Fig. 2 is. avert-ical section onthe line 2 .2 of Fig. 1-. Fig. 3 is a 3+8iof Fig 1. Fig. llis a 4+4 of Fig. 1. Fig. 5 is a 5 OfFlg.:4:. Fig. 6 is a-vertical section .on the line 6'6 of Fig.2 showing parts broken away.

Fig. 7 is an enlarged detail, partly in side elevation and partly in section of the counting mechanism. r i I Fig. 8 is 'a "detail section on the l1ne-8-8 ofFig.7." Referring more particularly to the drawings, the improved discharging. and countvertical section on the line vertical section on the line vertical section on the line 1923. Serial No. 636,613.

ing mechanism is particularly designed for use in connection with any suitable type of paper folding mechanism, and thepaper is received in the discharging mechanism from the cutters which may be of any approved construction, but which in the present invention comprise knife carrying rollers. The cutting rollers 1, cut the folded paper into proper lengths, and the cut and folded paper .is discharged from the rollers 1 into a trough 2 in an edgewise manner and as each individual folded paper is deposited into the trough 2 it is moved outwardly therein by the follower 3. The follower 3 is carried by a slidingbar 5 which is in turn slidably supportedby suitablev bearings 6. The bar 5 is connectedby means of a pivoted operating rod 7 to aneccentric 8 which is rotated by rotation, ofa shaft 9. The shaft 9. may be rotated from any suitable power source and the proportion and the eccentric of the speed of rotation of the shaft is such that the follower 3 will be moved forwardly atthe proper time to force the folded cutv paper outwardly inthe trough- 2,- as it is de livered from the. rollers 1...

The follower 3 is provided with transversely extending slots .11 extending therein fromonefside which are adapted to receive in a suitable slideway. 19 beneath the trough I 18 and is vten'sioned to ,move the arms 12 inwardly through suitable openings 21 in the trough 2, and behind a folded cut piece of paper as it is forced outwardly by the fol-" lower- 3 so as to prevent the folded paper from falling backwardly when the follower 3 recedes for forcing the next cut piece of paper outwardly. The armsv 12 are forced out of the trough 2 and out of the path of the folded .piece of paper, upon the forward movement of the follower}, by the engagementofthe cam roller 15Xwith the cam surfaces- 16 which cain surface is cut to perform-this function;

A. counter structure is provided for counting the'cut and folded piecesfof'paper delivered. to the trough 2 and, it comprises a 2. A'spring 20 is connected to the slide bar vertically movable bar 23 which has a cross head 24 upon its upper end. The cross head 24 is recessed longitudinally as shown at 25 to engage and receive one of the folded pieces of paper. The bottom 26 of the trough 2 is provided with a recess 27 into which the cross head 2' 1 normally rests. The bar 23 is pivotally connected as shown at 28 to an angle bar 29 which is in turn connectedto a slide 30. The slide 30 is slidably mounted upon the bar 31 andit has a rack 32 formed on one face thereof, theteeth of which are adapted to be engaged by the tooth 33 of the gear 35 for moving the slide 30 upwardly upon engagement of the tooth 33 with the rack 32. It will be noted that the gear 35 has only a single tooth 33, but it is to be understood that it may be provided with two or more teeth at proper spaced. relation, iii-desired and depending upon the frequency at which it is desired to move the counting bar 23 upwardly. I

The countingbar 23, will move in an are, on its pivot 28 on angle bar 29 which movement is necessary owing to the fact that the paper engaged by the head 24 will be moved along the trough 2 during the time that it is engaged by the head. The upward movement of the bar 23 will forcethe folded cut piece of paper which is engaged by thehead 24 upwardly disposing its upper edge above the upper edges of the remaining folded pieces of paper thereby clearly distinguishing it, and by regulating the speed of operation of the gear 35 relative to the speed of delivery of the folded pieces of paper to the troughs 2, it will be noted that anypre'determined number of folded cut piecesof paper may be permitted to' pass along the trough 2 before the counting bar 23 operates The trough 2 is relatively long and a relatively large number ofthe folded cut pieces of paper accumulate therein and itis to be understood that the folded cut pieces of paper may be taken from the'trough and bound into any suitable type of bundles and that the forcing upwardly of one of the papers after the passing of a pre-determined number of them over or beyond the bar 23 will permit 'definite accurate mechanical counting of the folded cut pieces of-paper.

' The bar 23 is returned to its normal downward position by a spring 36, while a spring 37 is provided for returning the slide 30 to its normal downward position. The return of the bar 23 to its normally downward positransmitting means 44. The ratio of the worm 42 and ,worm gear 4E1 will regulate the speed of rotation of the gear 35' and consequently regulate the intervals of operation of the counting bar 23. v

From'the foregoing description taken in connection with the accompanying drawings itwill be apparent that a mechanism has been provided by means of which cut and folded pieces of paper may be discharged from any suitable type of folding and cutting mechanism, in an effectively easily'handled manner, and in such manner as to prevent interference of one piece of paper with the successive dischargig of other out and folded pieces, and also that a mechanism has been provided to accurately and mechanically count the discharged folded and cut pieces of paper.

In Figs. 1 and 2 of the drawings a mechanism is shown for adjusting one of the cutting-rollers 1 relative to the other, and this mechanism comprises a feed screw 50 carried by the supporting frame 51 of the mechanism and connected to the bearing box- 52 in which the shaft 9 rotates topermit limited adjustment of one of the rollers 1 relative to the other.

It is, of course, to be understood that the invention may be constructed in other mane ners andthe parts associated in different relations and, therefore, we. do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described our inventiongwhat we claim is V V 1 1. In combination, a receiving trough for receiving folded cut sheets of paper, a follower for forcing. the paper through the trough, .means for "operating said follower, a plurality of fingers movable transversely of the trough for engaging and supporting the folded sheets of paper delivered to. the trough in upright position upon rescinding movement of the follower, and means for moving said fingers from said supporting position, said last mentioned means includ ing a driven shaft, a cam carried by the shaft and operable therewith, a :member movable toward the trough and's'upporting the fingers, a head formed on one 'endportion of the member and operable by the cam for moving the fingers from said supporting position, and'means for moving said member and head in an opposite direction to dispose the fingers in said supporting position. i 7

In combination, a receivlng trough for receiving folded sheets of paper, a follower means for operating said follower, I and means operable by said follower operating means for operating said counting bar, said 7 last mentioned means including a movable rack,and a pivotal connection between the rack and the counting bar.
